NUMBERING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 690,170, dated December 31, 1901. Application filed June 24, 1901. Serial No. 65,794. (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE H. MILLER, a citizen of the United States, and a resident of Norwalk, county of Huron, State of Ohio, have invented certain new and useful Improvements in Nu mbering-Machines,of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in numbering-machines; and the objects of the invention are to provide means for printing in numerical succession upon paper slips or pages figures or characters, and I accomplish my object by means of the printing-heads and rotating mechanism therefor with the mechanism for bringing each character into engagement with the tympan, as hereinafter described, shown in the accompanying drawings, and specifically pointed out in the claims.

In the accompanying drawings, Figure l is a plan view of my device. Fig. 2 is a transverse section of the same on line a a, Fig. 1; and Fig. 3 is a central longitudinal section of printing-head.

In the views, 1 is a shaft upon which the printing-head 2 is loosely sleeved. 3 is a sleeve secured to this shaft, shown located partly within the hub 4 of the head, which turns freely upon it and is kept in position thereon by means of the shoulder 5 at one end and the plate 7 at the other.

Upon the inner sleeve 3 is secured the arm 6, at the outer extremity of which is pivoted at 8 the roller 9, which is so arranged as to force outward the periphery of the head as it passes. The periphery of this circular head is furnished with raised type T, comprising the characters to be printed and shown as fifty in number. This is formed of a band of thin spring metal or other elastic material,

so that as the roller 9 passes about the inner surface it will force outward each type in succession and after the impression has been made the type will return automatically to their place.

Below the printing-head is placed the tympan-wheel 10, mountedupon a parallel shaft 11, and between the head and tympan-wheel passes the slip of paper 12 to be printed upon,

which the roller will press the type T against as the tympan-wheel comes diametrically in line with the roller. In order to force outward each type on the printing-wheel in succession, I provide the following arrangement of gearing to bring each type within the diametrioal line of printing:

13 is the drive-pulley, secured to the shaft of the printing-head.

14E is a gear upon the shaft 1, having the same number of teeth as there are numbers or type upon the periphery of the printinghead.

15 is a gear upon a parallel shaft 16. This gear engages the gear 14 and is provided with the same number of teeth. 17 is agear upon the parallel shaft 16, which engages a corresponding gear 18 upon the printing-head. The numbers of the teeth in these gears 17 and 18 vary, one having one more tooth than the other-that is, if one gear has fifty teeth to correspond with the number of type on the printing-head the other would have only forty-nine. In this application I represent that gear on the printing-head as having fifty teeth and the gear upon the parallel shaft as having forty-nine teeth. It will be obvious, therefore, that when the shaft 1 and arm 6 and roller 8 make one entire revolution the printing-head will make one character less than an entire revolution, since the number of characters corresponds with the number of teeth on the printing-head.

It will readily be seen that any number of printing-heads and actuating-gear therefor can be placed upon the shafts 1 and 16 and as large a number of type or characters as desired upon the head.

The position of the printing-head and tympan may be reversed, placing the printinghead upon the lower shaft and the tympan upon the upper.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a rotary printing-head, the combination with the body portion thereof, of a periphery comprisinga thin sheet of elastiomaterial, character type upon the exterior of the periphery, a gear upon the body portion of the head, a shaft over which said head is sleeved, a radial arm secured to said shaft,

and a roller on the outer extremity of said arm arranged to press outward whatever por-- tion of the said type-sheet. it may come into contact with, substantially as described.

'2. In combination with a printinghead provided with elastic periphery and type characters thereon, a central shaft upon which said head is loosely sleeved, a radial arm secured upon said shaft, and a terminal roller arranged to press outward the periphery wherever it comes into contact therewith, a tympan-wheel adjacent to said head, and means for rotating said head and arm at a 'difierent rate of speed, whereby a new character will be presented to the tympan-wheel and its impression made upon the slip at the moment of diametrical coincidence of the roller-arm, the type, and the tympan-wheel, substantially as described.

3. In combination, a printing-head provided with an elastic periphery and type characters thereon, a driving-shaft loosely passing through said head, a radial arm secured to said shaft, and provided with a terminal roller arranged to press outward whatever portion of the periphery it may engage, a tympan-wheel adjacent to said head, and means for rotating said head and arm at different speeds whereby each type character will be brought into contact with the slip and tympan in succession, comprising a shaft arranged parallel to the driving-shaft, engaging gears on the said shaft, provided with the same number of teeth as there are character type on the printing-head, and engaging gears, one on the printing-head and one on the parallel shaft, one of which is provided with one tooth less than the other, substantially as described.

In'testimony whereof I have signedmy name to this specification in the presence'of two subscribing witnesses.

. GEORGE H. MILLER."
